Justin.tv is the famous site with hundreds of tv streaming and it allows to create own web tv streaming too.
In these days is happened that on broadcasting sport events (in particular football matches), after some seconds after the begin of the stream, a message appear, in practice says to become a Premium user, pay a sum of about 70 dollars to 99 per year.
The message says that it has reached the maximum number of streams for your country.
So it’s easily thought that using an IP address from another country you can continue play the stream. So you need a free solution that i reviewed in this past article to bypass the limit! (the software UltraSurf is particularly recommanded)
Naturally you should have more than a good connection, because using these solutions affects the speed and so specially for the realtime streaming.
[UPDATE]
Justin.tv has adopted countermeasures so this article written by now is no more valid, to use this service you must become a Premium subscriber.
